GAUGING APPARATUS.

Application led April 19, 1822.

To all whom t may concern.'

Be it known that HEYMAN RosnNBnne, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Gauging Apparatus; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others'slilled in the art to which it appertains to maire and use the same.

rlhis invention relates to improvements in measuring apparatus of the type especially adapted for co-operative use with punch, and the primary object in view is the accurate and successive location of material relative to the punch for enabling the formation of apertures in the material in certain predetermined and exact relation to each other.

With this and further objects in view as will in part hereinafter become apparent and in part be stated, the invention comprises certain novel constructions, combinations and arrangements of parts as subsequently specified and claimed.

arm 3 carrying the guiding head 4L through which slidingly extends the punch bar 5 carrying the detachable punch bit 6. The punch bar 5 is guided within the head 4l and held thereby against other than axial movement, and the upper end of the punch bar is pivoted at ',7 between the side plates of an eccentric 8 carried by an operating lever 9, the lever being pivoted at 10 to a pair of linlrs 12. The linlrs 12 are arranged at the opposite sides of the head 4 and pivoted thereto at 13 so as to compensate for lateral movement' of the eccentric 8 while enabling the eccentric to eifect the wedging or camining thrust of the punch for producing the punching stroke of the punch bit 6. A stripper 111 is preferably employed and arched al1-out the lower portion of the punch, and is carried by upstanding arms 15 arranged at the opposite sides of the head 4- and clamped thereto by plates 16, engaged by wing nuts 17 threaded onto laterally eX- tending bolts passing through the respective plates 16.

The free end portion of the table 2 carries a removable die or tubular member 18, arranged co-aXially of and adapted t0 cooperate with the bit G. A set screw 19 is threaded through a portion of the table 2 and engages the die receiving sleeve 18l and detachably retains the die in place. The edges of the table 2 are preferably beveled to form slide bars 2O on which is slidingly mounted the collar 21 of the arcuate stop 22. The collar 21 underhangs the table 2, but isvopen at its lower portion to accommodate the bracing fillet or web 2lconnecting and formed integral with the base of frame 1 and the under face of table 2. A set screw 25 is threaded through the collar 21 and engages one of the slide bars 2O for locking the stop 22 in any given adjusted position.

The base of the frame 1 is formesl with a squared passageway through which is slidingly entend-ed a similarly squared bar 26.

t will be apparent, of course. that the bar 26 may be otherwise polysided or otherwise shaped in transverse section so long as pos* s'essing a contour f correspondingr to the transverse contour of the nassafrewav anfl so shaped as to prevent rotation of the har. A set screw 27 threaded throuoh a oortiou of 4the base of frame 1 engages har 2G to loclry the bar at various points'A of lonnitudirial radicalement.- The outer fr ot har 26 extends into a socket 28 in a preferably circular plate 29, the plate 29 being thickened at the place of the socket 28 for providing sufficient space therefor. An appropriat'e rivet, pin, or other securing means 30 is passed through the Wall of the material about socket 2S and through the barv 26 for securing the parts together. The plate 29 has its Lipper face formed into a dial provided with graduations 31 arranged to facilitate the location of certain angles as will be hereinafter described. The plate 29 is centrally apertured, as indicated at 32 in Figure 3, andatubular bolt 34 extends throughsaid aperture and is engaged by a wing nut 35 for clamping the bolt to the plate. The head of bolt 34 is formed into a transverse sleeve 33 and a tubular upstanding sleeve: 36 above the sleeve A gauging pin 37 extends adjustably throughout the length of the lbolt 34 across' the sleeve 33 and through the sleeve 36, and is retained at various adjusted positions by an appro'- priate thumb screw 38 threaded through a portion of sleeve 36. The pin 37 is preferably provid-edwith a conical head 39 at its upper end.

The sleeve 33 is in the form of a square or other appropriately Vpo'lysided passageway through which slidingly extends the gage bar 40 having a central, longitudinal slot 41 permitting the bar 40 to slide longitudinally through the `sleeve 33, while the pin 37 extends transversely7 therethrough, the pin being accommodated in the slot 41. One end portion of gage bar 40 is provided with a stop 42, seen in Figures 2 and 4, for preventing th'e -bar 40 from being accidentally withdrawn through the sleeve 33. A gauging pin 43 extends through the opposite end portion of bar 40 from that having the stop 42, and a set screw 44 is threaded through a portion of the material of bar 40 into engagement with the pin 43 for locking the pin infvarious positions of longitudinal adjustments. rThe upper end of pin 43 is provided with a conical head 45. Projecting from, and preferably formed integral with the sleeve 33 is a pointer 46 having its point extending on a line at right angles to the longitudinal axis of the bar 40, so that, when the pointer 46 is brought into line vwith any one of the graduation marks 31, the Ybar 40 will extend at right angles to the line of that mark, and the graduations 31 are calculated accurately relatively to such right angle so as to cause a circle described about the axis of rotation of the pointer 46 (when rotated as hereinafter described) toV .be equally divided into arcs varying in length according to the location of the particular graduation 31, each graduation being marked with a number indieating the number of arcs in a complete circle when tested orgaged by the bar 4() Vbit 6 as located incident to the positioning of the pointer 46 in line with the given graduation 31.

ln operation, the present improved instrument is designed to Vfacilitate accurate division of circular plates or bodies into equal arcs. so that the bodies may be perforated with openings spaced accurately and uniformly, and this result may be accomplished without the use of a templet. The apparatus is especiallyY well adapted for use in perforating ceiling plates, canopies, and other fixtures for electric light equipment and. other similar devices. As indicated in dotted lines in Figure l, the work 47 may be any appropriate, substantially disc-shaped body in which a central aperture is first formed and the plate is arranged with the conical head 39 extending partway through the aperture. The work 4i' is thereby centered relative to the punch and the operator punches a hole near the periphery of the work, and then turns the work angularly until the perforation 'surrounds and the work rests upon the head 45 o t' pin 43. Another perforation is then formed in the work 47, and the Work is again turned, and so Y*onV until the circle has been completed. v However, before'the iirst aperture formed is placed over the head 45, the bar 40Y will have been located angularlygf as required for insuring the number of apertures desired. Toeft'ect the acc `rate angular location for this result, it is only necessary for the operator to loosen the nut 35 and swingthe bar 40 with the bolt 34 and sleeve moving pivotally on y the longitudinal axis of the pin 37 until the pointer 46 registers with the graduation 3 bearing that indicia indicating the number of :fipertures desired. ifuonlv four apertures :are required, the bar 4t) willobe moved until the pointer 46 points at the graduation 31 bearing the digit 4, where upon the bar 40 will extend at right angles to the bar 26 and a circle described about the axis of rotation of the bar 40-and sleeve will have an are representing oneffourth of vthe circle lying between the axis of the bar 26 and the axis of the bar 40. As the of the bit 6 is coincident with the axis incident with the axis of bar 40, the aperture surrounding the head 45 will center upon `the head and thus locate the work 47 with the center of the aperture spaced from one-fourth of the circumference of the circle 'described fby the work. If a less number of apertures than four is required. the angle between the bars 26fand of course, that whenever the bar 40 is adjusted for gauging any given number of apertures, the nut 35 is tightened as soon as the pointer 46 is brought into register with the required graduation 31, It should also be understood that the pin 43 is kept lowered and out of the way until the first aperture near the peripheral portion of the work 4T has been formed and is to be placed upon the head rEhe pin is then raised into place and the screw 44 tightened to hold the pin in its proper position.

While in Figures 1 and 2 the invent-ion has been illustrated as used in conjunction with circular work, it is also as effectively useful for straight work, such as strips or sheets. The location of the parts, when operating in conjunction with straight work, is indicated in Figure 4. To bring the parts tothis position from that shown in Figures 1 and 2, the set screw 27 is released and the bar 26 is slid inward until the axis of pin 37 is brought into register with the axis of die 18. To insure accurate registration, the head 39 of pin 37 is preferably inserted into the lower open end of the bore of die 18 and centered there by virtue of the conical form of the head 39. This position of the parts is indicated in Figure 4. When so positioned, the bar 26 is locked by the tightening of the set screw 27, and the pin 37 is then preferably lowered to leave the passageway of die 18 free for. the discharge of blanks stamped from the work. The strip or sheet representing the work is indicated in dotted lines at 48 in Figure 4, and the operation, after the bar 26 with its plate 29 have been properly located, consists in adjusting the bar 2O longitudinally until the axis of pin 37 is located laterally ofthe axis of die 18 the exact distance required between centers of openings to be formed in work 48. Since the work is straight, the bar 40 must be set at right angles to the bar 26, and, therefore, the pointer 46 will be placed in register with the graduation 31 bearing the digit 4. The bar 40 being locked in this position against swinging movement by the tightening of the nut 35, the pin 43 is adj usted to the raised position indicated i'nFigure4` and, the first perforation having been made in the work 48, the work 48 is moved over and placed with the head 45 of pin 43 extending through and centered in said perforation. The work 48 is then again perforated and moved over untilthe new perforation is placed for centering about the head 45, and the operation of perforating the work 48 is thus continued, the apertures formed by the punch bit 6 being spaced on centers equal to the distance between the axes of pin 43 and die 18. Of course, gradu- -ations may be placed on the bar 40 for indicating such distance, but for all practical purposes it is found sufficient to measure by the use of a steel tape or other rule the distance from the tip of the head 45 to the centering point at the lower end of the punch bit 6. lt should be observed, of course, that the bar 40, while free to slide within the sleeve 33, llits the sleeve suiii ciently snugly to have the required friction for retaining the bar 49 in any given position of adjustment longitudinally. Should the wear of the parts reduce such friction sufficiently to necessitate other precaution, a set screw may be passed through the material of sleeve 33 into engagement with the bar 40.

In Figures 5 to 8 inclusive is illustrated the same invention shown in the preceding figures with the centering pin carrying the dial head and 'with the gage har hent at right angles for adapting the parts for use in gauging canopies and tubular and cylindrical structures. In these figures the same punch is employed and the same reference numerals are applied to the parts of the punch shown., and the same description, applies. The same bar 26 is utilized with its plate 29, tubular holt 34 having the trans-- verse sleeve 33, and the upstanding sleeve or colla-r 36 provided with the set screw 38. These are the identical parts shown in the preceding vFigures and the pin. 37 extends through and is retained in the tubular bolt in the same manner as pin 37, but pin 37 instead. of terminating with an upstanding conical headvis provided at its upper end with a disc 29 having graduations 31 arranged to function do the gradnations 31 save that the graduations 31 are .arranged on vertically-disposed face instead of a horizontallydisposed face. A bolt 34 extends through the center of disc 29 and is engaged at its outer end by a wing nut 35 clamping a collar 49 against the cuter face of the disc 29. Collar 49 carries a pointer 46 designed to function in the same manner as pointer 46, except in vertical plane instead of a horizontal one. rThe collar 49 is formed with a squared opening through which a squared portion of the bolt 34 extends` so that the pointer 46 will revolve with the bolt. he inner end portion of holt 34 is formed into head providing a transverse sleeve adapted to function the same as'sleeve 33 except for the dii2m ference in the planes, and the head is finished with a conicallyrpointed portion 39. A gage bar 40 is slidingly mounted through the sleeve 33 and intermediate its ends is bent form a right angle arm 40 on which is slidingly mounted a sleeve 50 carrvinv` a Gauvin in 43 havino a conical s b D b i C head, 45. A set screw 41 locks the sleeve 59 in any Igiven adjusted position along the arm 40". The work indicated by' the canopj7 51 is placed in position surrounding the outer end portion of the table 2'with the inner end of the canopy abutting against the stop :22, the canopy having already had a centering aperture formed in its outer end. The bar 26 is slid inward or outward and the pin B7 upward or downward according to whether the work 5l is smalleror larger, until the, conical point 39 is passed into the centering aperture. in the-*outer end ot the work 5l, and the work is centered thereby. rlw'he gage bar d0 is .then swung' vertically until the pointer 416 indicates the particular graduation 3lbearing the digit representing` the number of lapertures to be punched in the work 5l, the bar 40 being slid out far' enough to have the arm d0 in position for having the head4t5 clear of the work. ,-in aperture is then punched in the work 5l` and the work is then turned until the aperture just punched comes into line with the head 45', and the bar flO" then slid inward until the head d5 centers itself in Athe aperture just punched in the work 5l.

rlhe work isothe-n again punched, the bar 40 slid back. the work revolved and the second opening centered on the head 45', and the punching Aprogresses until completed.

lt should lie-'obvious from the. foregoing that ycanopies or other similar work 51 of a wide range of sizes ma;rbe thus punched with any number of apertures desired with accurately7 and uniformly spaced centers, the gauging apparatus beingr adjusted only when a diiferent sized piece of work is introduced from that which has been operated upon. y

Nut 35 is, of course, released whenever bar 40 is to be swung angularly, and is again tightened to clamp bolt 3ft in the new position as soon as pointer'lt registers with the particular graduation 3l required.

It is clear also that while the invention has been illustrated as applied to a punching machine in the sense of a machine which cuts holes by a single punching stroke, it is just as applicable to an aperture-forming machine or marker of any other class.

An essential feature ofv construction in the embodyingof the present invention, as should be apparent from the foregoing, is the provision of means co-operating with a punch orother marker for readily and accurately establishing or measuring the distance between the axes of an aperture punched in work and an aperture to be punched therein. Such means is preferably adjustable, so as to facilitate measurement of such axes where work is of different sizes, or where the apertures in one piece of work are to be of a different distance apart from those in another piece of work, or otherwise provide for indicating uniform Vdistances with ease, speed and accuracy. When it is desired to save the labor of measurement by lcurved or circular work, the distance-establishing means indicates accurately the length of an arc of a circleproduced to intersect the axis of the aperture already punched and y the axis of the aperture to be punched, such arc being of a'length to terminate with said two axes. Such arc may, of course, be measred by its Vchord as well as by its own length7 and, while with circular work the distance establishing means may thus ybe adjusted and/measured on the chordinstead of the arc, the relative angularity of a straight line produced to intersect the axis of the worlr and the axis of the punch to a straightv fline produced to intersect the axis of the work and the axis of the distance-establishing means will always form a basis for ready and accurate calculation of therproper position for the location of the distance-establishing means.-

Hence, such angularity is taken into account in the embodiments of the invention illustrated in the drawings, and the dial graduations in each case serve `merely to .enable accurately and easily varying such angularity with `each required variation Vin the distance. kBecause it is usually desirabler the circle into equal parts, but, if under any Y conditions, the user should desireV the first e l and last apertures to be Vspaced a distance apart different from the distance between each two otallofthe other apertures, he would place pointer 46' or 46, asthe'case may be, between two ofthe grad uation marks 3l or 31 instead of in register with one of them. Uniformity in spacing would still occur between all apertures except the first and last. y
